Those pop-ups are commonly either browser notifications or scam-style alerts, not proof that McAfee is actually installed or that the PC is infected.
Try these steps in order:
- In Microsoft Edge, check whether pop-up blocking is enabled:
- Press Alt + F > Settings.
- Go to Cookies and site permissions > Pop-ups and redirects.
- Make sure Block (recommended) is turned on.
- If the pop-ups continue, turn off suspicious website notifications in Edge:
- Open Edge.
- Go to Settings > Cookies and site permissions > Notifications.
- Remove or block any websites that are not recognized or were not intentionally allowed.
- Check Edge extensions:
- Press Alt + F > Extensions > Manage extensions.
- Turn off all installed extensions temporarily.
- If the pop-ups stop, turn extensions back on one at a time to find the one causing it.
- Update Edge:
- Press Alt + F > Settings > About Microsoft Edge.
- Let it install any available update, then restart Edge if prompted.
- Block third-party cookies:
- In Settings > Cookies and site permissions > Manage and delete cookies and site data.
- Turn on Block third-party cookies.
- Clear browsing data in Edge.
- Run a malware scan with Windows Security.
Important:
- Microsoft notes that some pop-ups are actually website advertisements made to look like system warnings.
- Microsoft will never call unexpectedly to say there is a problem with the computer.
- If the alert asks to call “support” or pay immediately, treat it as a scam.
If McAfee is not intentionally installed, these alerts are especially likely to be browser notifications or deceptive ads rather than real antivirus warnings.
